My mother would rent X rated movies and we'd watch them together to teach me about sex. We must have watched this one 100 times. I learned how to eat pussy by watching the scene with Ginger Lynn & Susan Hart, then practicing on my mother, learned how to fuck by watching the next scene with Janey Robbins, although my mother's pussy was nice & hairy, not shaved like Janey's. And of course I learned how to fuck her in the ass by watching the Ginger & Marc Wallice scene.
